Land Measuring Units in Pakistan

Karam (کرم) 

1 karam = 2 ft. steps = 5.5 ft. = 1.67 m
1 sq. Karam = 5.5 x 5.5 ft. = (5.5)2 ft.2 = 30.25 ft.2 or
1 sq. Karam = 1.67 x 1.67 m = (1.67)2 m2 = 2.679 m2

Marla (مرلہ)

1 Marla = 9 sq. Karam = 9 x (5.5)2 ft.2= 9 x 30.25 ft.2 = 272.24 ft.2 or
1 Marla = 9 sq. Karam = 9 x (1.67)2 m2= 9 x 2.789 m2 = 25.10 m2

... 1 Marla = 9 sq. Karam = 25.10 m2 = 272.24 ft.2

Kanal (کنال)

1 Kanal (K) = 20 Marla = 20 x 272.24 ft.2 = 5444.8 ft.2 (since, 1 Marla = 272.24 ft.2) or
1 Kanal (K) = 20 Marla = 20 x 25.10 m2 = 502 m2 (since, 1 Marla = 25.10 m2) or
1 Kanal (K) = 20 Marla = 20 x 9 sq. Karam = 180 sq. Karam (since 1 Marla = 9 sq. Karam)

1 Kanal (K) = 20 Marla = 180 sq. Karam = 502 m2 = 5444.8 ft.2

Bega (بیگا)

1 Bega (B) = 4 Kanal = 4 x 5444.8 ft.2 = 21779.2 ft.2 (since, 1 Kanal = 5444.8 ft.2) or
1 Bega (B) = 4 Kanal = 4 x 502 m2 = 2008 m2 (since, 1 Kanal = 502 m2) or
1 Bega (B) = 4 Kanal = 4 x 180 sq. Karam = 720 sq. Karam
(since, 1 Kanal = 180 sq. Karam)

1 Bega (B) = 4 Kanal = 720 sq. Karam = 2008 m2 = 21779.2 ft.2

Acre (ایکڑ)

1 Acre = 8 Kanal = 8 x 5444.8 ft.2 = 43560 ft.2 (since, 1 Kanal = 5444.8 ft.2) or
1 Acre = 8 Kanal = 8 x 502 m2 = 4016 m2 (since, 1 Kanal = 502 m2) or
1 Acre = 8 Kanal = 8 x 180 sq. Karam = 1440 sq. Karam(since, 1 Kanal = 180 sq. Karam) or
1 Acre = 2 Bega

1 Acre = 2 Bega = 8 Kanal = 1440 sq. Karam = 4016 m2 = 43560 ft.2

Hectare (ہیکٹر)

1 Hectare = 2.47 Acre

Lat (لاٹ)
